To (17 iclmm it may concern Be it known that l. RUIIARI) liics'rniiVVIL- cox. a citizen of the United States. residing at hiterbury. in thecounty of New Haven and State of Connecticut, have invented certain newand useful Improvements in Mechanical Movements, of which the followingis a specification, reference being had therein to the accompanyingdrawings.

My invention relates to new and useful mechanical movements. having moreparticiila r reference. to mechanism for operatinga header of thattypewherein a wire rod is automatically fed into the machine and cut offinto pieces of predetermined lengths. one end of which is upset so as toform a head, and the whole. when completed. forming a bolt olrivetblank.

the punches connected therewith will tilways occupy a horizontalposition irrespectire of the vertical position of the slide;

means for adjusting the position of the slide in relation to the cam:means for iockin; the punch slide against movement while the punches arestriking their effective blows:

and to so construct and design all of the L several parts that they maybe economically constructed and readily asseinblcdql To these, and otherends. myjinvention consists in the mechanical movement. having certaindetails of construction and coinbinations of parts. as will behereinafter described and more particularly pointed out in i V i dieblock and the underside-of the cap, withthe claims.

mounted upon suitable legs i. in whichiis rotatably moiinted't'hc crankshaft with the driving wheels fixed thereon. and-iii A which the gate .3is slidably mounted, deriv It) ing its movement from said cranlcsli'a ftthrough the pitman (3 and toggles T and 153. the former heing connectedwith the bed a'itfl the latter with the gate. The timing shafft 9 isrotatable in the bed at a speed one-third 7 of the crank shaft. bein"driven frmira pinion 10 n said crank shaft, the teet-li df which meshinto those of the gear ll liked on the shaft 9. 'hi le l have only shownit toggle actuated gate my invention equally applicable to a machinehaving a crank a c tiiated gate. or in fact with any reciprocatin; gate,irrespective of the iii-.iniicr by which its motion is derived. Lyingwithin i t a pccket in one end of the bed 1 is a die block 12 that isvertically adjustable therein by means of the-screw l3, and is formed insubstantially the form of a figure L, inside elevation, as shown in Fig.'9. and scoured L thereto, by means of the bolts let. is the cap 15.This cap. when secured in place, *leaving an open space betweenthcbottom ofit-he in which are mounted the dies l717', the backingblocks 18-48, and the filling blocks 19 19, all being held againstendwise movement by the plates 20, secured by the screws 21. Thearrangement and operation of the several dies and backing-and fillingblocks is as usual in this type of inachine, and the dies are movedapart by the usual separators 22 that are slidably mounted in the holes23 in the cap l5; and are normally moved downward by the pressure of thei springs 24giwhieh are secured at one end to tl'iefixed block 25.W'Vith thegdic block. as' herein shown and describednaccess to thegdiesand blocks is conveniently and quickly had. by sinipiy loosening thenuts 26 upon the bolts 14 and l moving the cap away from the block 12,which is accomplished without disarranging the relative positions of thedie block and bed of the machine.

Vertically movable in the gate 5 is the slide 27, having a late-rallyprojecting lip 28 at its lower end, and upon the face of which issecured the punch block 29, having the punches 30 and 31 fixed therein.Movement is imparted to said slide through the rock shaft 32, rotatablein the journal boxes 37 fixed to the bed 1, and between the arms 33 ofwhich the guide block 34 is mounted upon the fixed shaft 35, said guideblock being grooved at 36 for the reception of said lip 28. Mounted uponsaid rock shaft is the roll arm 38, having the offset lugs 39 at oneend,-between which the arm 40, integral with the rock shaft 32, isadjusted, through the screws 41, and is secured in any of its adjustedpositions by the bolt 42, and carrying at its opposite end a roll 43that is mounted upon an eccentric stud 44 journaled in said arm, Thisstud is adjustably secured in said .roll arm by a key 45 that passesthrough a key-way 46 and impinges against one of the several flat faces47 upon said stud, the nut 48 securing said stud in its adjustedpositions. The roll 43 projects into a groove 49 in the cam 50 which isfixed to the timing shaft 9. A shaft 53 is fixed in the ears 52,integral with the caps 51 of the journal box 37, and has a link 54thereon that is secured between the arms 55 integral with the guide 34by the pintle 56. As the cam 50 rotates, movement is imparted to therock arm 32 through the roll arm 38, and a vertical movement to theslide 27 through the operative connection between the guide block 34 andthe lip 28 upon said slide. The link 54 always holds the guide block 34in a horizontal position, irrespective of the position of the rock arm,and during the reciprocation of the gate 5, the lip 28 moves in thegroove 36 in said guide block. By this linkage connection the slide iscapable ofmovement in two directions, at right angles to each other,without cramping or tilting, a common objection in heading machinesheretofore made, which cramping and tilting moves the punches so thatthey are not in their proper positions when a blow is struck. To offsetthe weight of the slide 27 and punch block 29 which are upon one side ofthe rock shaft 32, I have provided a weight 77, which is shiftable uponan arm 76 upon said shaft, and secured in any of its adjusted positionsby the screw 78. This counterweight reduces materially the wearoccasioned by the movement of said slide and punch block, and providesfor its easy operation, with the minimum application of power. Therotary adjustment of the cam r011 43 in connection with the arm 38 pro-.

vides for a limited variation of the length of the stroke of the slide.The punch slide is locked while the blow is being struck, through thelocking slide 79 that has a reciprocatory movement in the sleeve 57mounted in the gate 5, and provided with a lip 58 on its forward end,which enters a groove in the locking blocks 59 and the groove 60 in theback of the slide. Said locking blocks are mounted in pockets which lieat a slight angle to the top and bottom of the slide, as shown in Fig.11, are adjusted laterally in said pockets by the screws 61, and aresecured in their adjusted positions by the key 62 that is secured by thebolt 63 and nut 64. The vertical position of the slide 27 is variedslightly by lateral adjustment of these blocks 59 within the slide so asto insure the registering of the axis of each one of the punches withthat of the wire while being operated upon. A reciprocatory movement isimparted to the locking bolt 56 through the rock lever 65, pivotallysecured to the gate 5 by the stud 66, said lever having three arms, oneof which terminates in a head 67, that lies within a block 68 movable inone end of the locking bolt beneath the cap 69 and having cam rolls 70upon the other two arms, which lie against a cam 71 mounted on the cap72, fixed to the bed 1. Said cam has a slight lateral movement upon thecap by means of the spring 73, which bears at one end against said camand at the other end against the lug 74, a screw 7 5 threaded throughsaid cap forming a fulcrum, whereby the tension of the spring mav bevaried. As the te 5 reciprocates, the rolls 70 ride upon the cam 71, andimpart a rocking movement to the rock lever 65, and through which areciprocating movement is imparted to said locking bolt, the operationof the locking bolt in relation to the slide being such, that when theslide is at rest and about to strike a blow, the lip 58 will enter thegrooves 60 in either of the locking blocks 59 and hold said slideagainst vertical movement. The relation of the blocks 59 with thepunches 30 and 31 is such that the lip 58 only engages with the groovestherein when a blow is being struck, that is, in the type of mechanismherein shown, during the first two horizontal movements of the gate, andthe third movement, when no blow is struck, the lip enters the groove60, which can, and usually is, much larger than that of the lip 58, asit is not important that the slide should now be held against a slightvertical movement.

- The punch block 29 is constructed and secured to the slide 27 so thatduring the third forward movement of the gate, all of said punch blockis above the line of the Wire, and the entire space between the front ofthe slide 27 and the face of the dies is open,

so that a blank, of substantially the same length as said open space,can be readily ejected.

In operation, the wire is fed into the machine by any .type of feedingmechanism,

(not herein shown), and is cut off into predetermined lengths by equallywell known mechanism. The first forward movement of the gate brings thepunch 30 in contact with the projecting end of the wire and upsets theend thereof, and the second blow com pletes said head, and at the thirdmovement the finished blank is ejected beneath the punch block and dropsout of the machine, thus two of the three movements striking aneffectiveblow and the third being a miss while the blank is being ejected.

As previously mentiomai, my,invention may be used in a machine, whereinthe punch strikes an effective blow at each forward movement of the ate,and the blank ejected between two 0 such blows, such action beingaccomplished by merely changing the shape of the cam 50 and the ratio ofspeed between the crank and timing shafts.

Minor changes and alterations can be made within my invention, and Iwould therefore have it understand that I do not limit myself to theexact. construction herein shown and described, but claim all that fallsfairly within the spirit and scope of my invention.
